Loved it.
Star Wars: Rogue One was a great movie. All the twenty somethings in the family loved it as well. As the first Star Wars Movie that doesn't revolve around the characters of the original six movies I thought they knocked it out of the park. It is action packed and has the look and feel of a classic Star Wars movie. It revolves around how the rebels captured the Death Star plans which leads into Star Wars: A New Hope. Along the way there are plenty of surprises especially in who we see in the movie as well where the movie takes us and how it ties into the original trilogy. While we all know who it ends getting there is the fun part. The different characters introduced are great and fit right into the Star Wars universe.
SPOILERS AHEAD: I loved all the reference to the other movies and inclusion of different characters. You'll see Bail Organa return, Mon Mothma as well as other rebel leaders, while seeing Governor Tarkin and Princess Leia (the biggest reveal). There are others as well to include rebel pilots and C-3PO and R2-D2. You'll hear "It's a trap" and "I have a bad feeling about this" uttered as well. Some of A New Hope is explained as we find out that lead character Jyn Erso's father built in the Death Star's fatal flaw as a way to get back at the Empire. It was tough getting attached to the characters knowing that they may all die in the end (and they did) but it was for the greater good and lent more importance to what they ultimately accomplished.
I really enjoyed this movie. The somber tone underscores how it is different from others but it does a great job telling it's story which is important to the entire Star Wars franchise. In fact it literally hands you off to A New Hope as we see Princess Leia escape in her ship Tantive IV from the climactic battle right before what we know will be her capture but Darth Vader at the beginning of A New Hope. Good stuff and everyone should go see this movie.
